Connecting the relay

Describe the bug
After connecting all components, I think my relay isn’t switching. There is no led indicating change.
I have heated up my thermocouple from way below the set temperature, to above the set temperature, and I see no led indicating change.
The pinout in the readme states the ground should be connected to relay pin nr. 3. Is this correct? Shouldn’t this be the 5 volt?
Yes good spot i had mistakenly specified the pins wrongly, check again it's corrected now.
Just to confirm, are you using an arduino nano or an esp8266 ? Asking because the pinout in the documentation is catering for the nano only and you've opened the esp8266 related issue earlier.
Thanks, the pins are correct now in the README. Hoping to get my "Hobby Gaggia" next week, so I can build in the upgrade.
I am using the nano for now. You have convinced me about the simplicity of the project using the nano, and I will not use a esp8266 for now. Thanks for making the branch.
